the way Jackson did. Sweeney has said the filmmakers had considered doing what Gary Cooper did as Lou Gehrig in "Pride of the Yankees" -- have him wear a mirror-image uniform, shoot him running the bases clockwise, then simply reverse the negative -- but they couldn't afford to do so."
I was an ENT surgery resident working at the VA Hospital in Indianapolis at the time they filmed a lot of the baseball scenes at Bush Stadium, which was three blocks from the hospital. Our ENT Clinic secretary had several days off so that she could be a member of the crowd dressed in period costume. It only paid $20/day so they had to move the few live extras around the stadium to be in the background for action scenes. For the rest of the seats, they used cardboard cutouts.
Also, Ring Lardner was born in Niles, MI and his first job as a journalist was with the South Bend Times as a reporter covering baseball and Niles news. Writer/director John Sayles plays Lardner in the movie, and the two look remarkably alike.
